Even if he becomes a very big yogi, he has to undergo suffering, duhkhalayam asasvatam. This world is like that. For practicing this hatha-yoga, it requires much labor. It is not so easy. They are thinking that they have got this power, yogi, but it is exactly like if you want to become high-court judge, if you want to become prime minister — it is not so easy. You have to work very hard. Nobody gets all these posts so easily like [indistinct]. No. One has to work very hard. Duhkhalayam, you have to undergo. You want some very exalted post in this material, either as yogi, or karmi or jnani, it requires the hard labor. But a devotee, because he does not want anything like the karmi, jnani and yogi, for them, visvam purnam sukhayate. The whole material world is happy. Visvam purnam sukhayate.

So this is possible by Caitanya Mahaprabhu’s mercy. It is possible. Therefore Prabodhananda Sarasvati has given us this instruction, that yat karunya kataksa vaibhavavatam [Caitanya-candramrta 5].  It is possible to become perfectly cent per cent happy by the mercy of Sri Caitanya Mahaprabhu. Not even full mercy. If Caitanya Mahaprabhu simply looks over anyone, directly person will be happy as [indistinct]. Take mercy of Sri Caitanya Mahaprabhu and distribute it throughout the whole world. This is the Krsna consciousness movement.
